6` Claims. (C1. 155-179) The main objects of this invention are:

First, to provide a spring structure in which the frame though light in weight is very rigid in a horizontal direction or transversely of the cushion structure and at the same time may be formed of light stock and is braced so as to prevent sidewise swaying.

Second, to provide a spring structure having brace members in which the brace members are the U-shaped tie members II which are clamped 2 upon the bottom coils of aligned springs. It will be understood that in practice the bottom frame is greatly varied according to the particular requirements.

The top border frame comprises inner and outer frame members 5 and E preferably formed of fiat wire stock disposed fiatwise or with their flat sides horizontally. It should be borne in mind, however, that my improvements are securely attached to the rim and so that there 10 adapted to back cushion springs as Well as seat is no undue wear on the upholstery and they are cushion springs and the term horizontally as not likely to become detached or rupture through used herein is a relative term.

In Fig. 8, the structure has a cross brace 2U having upturned ends 2| secured to opposed side members of the frame, the same as the brace described. Particularly in larger cushions, this is a desirable feature. It is obvious that is may be used in combination with the braces 9 where additional bracing or tying is desired.

In the embodiment illustrated, the frame comprises complementary sections designated generally by the numerals 22 and 23, the ends of these sections being disposed in alignment. The ends of the frame members are inwardly bent to provide pairs of converging arms 24 and 25. The coupling members or clips designated generally by the numeral 26 are formed of sheet metal and have offset edges 21 in the intermediate side porticns thereof providing shoulders 28 engaging the edges of the frame members with the arms 25 of the frame members engaging the inner sides of these offsets. The edges 2,1 of the coupling members or clips are folded around the frame members and welded thereto at 29. These inturned edges 21 are indented at 30 between the arms of the sections to further clamp the frame members. This provides a very rigid and secure connection for the frame sections and one which is light in weightand does not result in objectionable projections.

It will be noted that the tongue I8 is tapered. IZlhis facilitates its wrapping around the arm as the edges of the tongue do not engage the edges of the opening and there is .no binding even if the tongue is slightly distorted in folding around the brace arm.

In the embodiment shown in Fig. 9, the clip 3i has portions 32 struck down from the edges thereof providing shoulders corresponding to the shoulders I2 described, the tongue 33 having only its tip portion tapered at 34. This shows another adaptation which is highly practical.

I have illustrated and described my invention in highly practical embodiments thereof. I have not attempted to illustrate or describe other adaptations which IV contemplate as it is believed that this disclosure will enable those skilled in the 'art to embody or adapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: v

1. In a spring structure, the combination with coiled body springs, of a tie member. of U-section clamped upon corresponding coils of a plurality of said springs, a top border frame comprising nat spaced inner and outer frame members, a clip of sheet metal connecting said spaced frame members and having oppositely disposed Oifsets in the side edges thereof, the ends of which constitute spaced pairs of shoulders in engagement with the adjacent edges of the frame members, the ends of said clip being clamped upon said frame members and rigidly engaging the latter to prevent relative rotation of the clip and frame members, a portion of the web Vof the clip between said offsets and between said ends of the clip being strucktherefrom to provide a clamping tongue', and a brace having laterally disposed arms terminating in inturned lugs, the arm at one end'of said b'racebeing clamped in the channel of said tie member, the

5. In a spring structure, the combination with body springs, of a borderframe. connected to said springs and comprising inner and outer frame members disposed in spaced parallel relation, a clip of sheet metal connecting saidframe members and having offsets .intermediate said frame members providing outwardly Vfacing. shoulders engaging said frame members, the ends of said clip being clamped around the frame members to coact with said shoulders in xedly connecting said frame members, the web .portion of,- said clip intermediate said fra-me members having abendable tongue struck out therefrom, said tongue being connected to said clip at its outer end, and a brace disposed below said clip and havingV a' laterally disposed portion secured thereto by said tongue, the end of said tongue connected to said` clip being in supported Vengagement., withthe outer frame member.

,6. A- spring structure comprising inner andV outer frame members disposed in spaced parallel relation, a bendable sheet metal clip connecting said spaced frame members and having intermediate portions thereof offset providing shoulders which engage the adjacent edges of the frame members, the ends of said clip being clamped -upon said frame members to clamp the same against said shoulders, the intermediate portion of said clip beingr slit between said frame members to provide a bendable tongue, and a brace having a laterally disposed portion secured to said clip by said benda-ble tongue.
